  • the distal end of the label tape 3 A having further progressed from the protruding state reaches and is brought into contact with the rotary shaft 650 and then, is started to be guided (substantially horizontally or slightly downward in this example) so as not to move further upward by the rotary shaft 650 . That is, in the present embodiment, the label tape 3 A is guided at a rotation position out of a rotation range from the first rotation position to the second rotation position.
  • FIG. 12D is a state of the rotation phase “180°” in which the rotation of the rotary body 620 further slightly progresses. From this state, the label tape 3 A is fed to the front while being further guided by the rotary shaft 650 .
  • FIG. 12E is a state of the rotation phase “270°” in which the rotation of the rotary body 620 further slightly progresses. From this state, the label tape 3 A further goes forward while being guided by the rotary shaft 650 , and the distal end portion of the label tape 3 A is in a state out of the rotation trajectory of the rotary body 620 . As a result, the label tape 3 A enters the cutting preparation completed state stably held in the feeding path, in which the lower surface is substantially brought into contact with the second edge portion 631 b , while the upper surface is substantially brought into contact with the lower part of the rotary shaft 650 . If the rotation of the rotary body 620 further progresses after this state, the label tape 3 A enters a cutting start state illustrated in FIG. 12A , and the similar procedure is repeated.
  • the introduced label tape 3 A is prevented from erroneously advancing toward the first edge portion 621 b side of the rotary body 620 and colliding with or interfering with the first edge portion 621 b before getting closer to the second edge portion 631 b .
  • the label tape 3 A can be cut stably (See FIG. 12A ).
  • the object to be cut can be guided without adding a new member.
  • a member different from the rotary shaft 650 may be newly provided. Such variations will be described by referring to FIGS. 13A to 13C and 14 .
  • a guide member 900 having a downwardly curved section is provided on the back surface of the first flat blade 621 of the rotary body 620 so as to protrude to the side opposite to the first edge portion 621 b , that is, toward the rotation axis O side.
  • the guide member 900 is brought into contact with the label tape 3 A from the one side (upper side in this example) in the rotating direction and guides the label tape 3 A to the other side (lower side in this example) in the rotating direction when the label tape 3 A is fed on the feeding path and further fed from the cutting position to the inside of the rotary body 620 similarly to the above.
  • the guide member 900 is arranged inside the rotation trajectory (see the two-dot chain line) of the first edge portion 621 b .
  • a center part in the axial direction (that is, the right-and-left direction) of the rotary shaft 650 is removed in order to install the guide member 900 .
  • FIGS. 14A to 14E similarly to FIGS. 12A to 12E , the guide behavior of the label tape 3 A by the guide member 900 is illustrated in order along the aforementioned rotation angle.
  • FIG. 14A is a state in which the rotation phase of the rotary body 620 is “0°”, and similarly to the above, the first edge portion 621 b is brought into contact with and rubbed with the second edge portion 631 b from the upper side, and cutting of the label tape 3 A is started.
  • FIG. 14B is a state of the rotation phase “60°” in which the rotation the rotary body 620 further slightly progresses from the above state.
  • the label tape 3 A on the front in the feeding direction of the cutting position is pushed by the front surface of the first base portion 621 a and further fed to the front, and the label tape 3 A on the rear of the cutting position is also fed to the front and introduced to the inside of the rotation trajectory of the first edge portion 621 b .
  • the distal end of the label tape 3 A protrudes substantially horizontally toward the guide member 900 inside the rotation trajectory.
  • FIG. 14C is a state of the rotation phase “120°” in which the rotation of the rotary body 620 further slightly progresses.
  • the distal end of the label tape 3 A having further progressed from the protruding state reaches and is brought into contact with the guide member 900 and then, is started to be guided (slightly downward in this example) so as not to move further upward by the guide member 900 .
  • FIG. 14D is a state of the rotation phase “180°” in which the rotation of the rotary body 620 further slightly progresses. From this state, the label tape 3 A is fed to the front while being further guided by the guide member 900 .
  • FIG. 14E is a state of the rotation phase “270°” in which the rotation of the rotary body 620 further slightly progresses. From this state, the label tape 3 A further goes forward while being guided by the guide member 900 , and the distal end portion of the label tape 3 A is in a state out of the rotation trajectory of the rotary body 620 . As a result, the label tape 3 A is substantially brought into contact with the second edge portion 631 b on the lower surface and enters the cutting preparation completed state in which the upper surface is located below the guide member 900 and stably held in the feeding path. If the rotation of the rotary body 620 further progresses after this state, the label tape 3 A enters a cutting start state illustrated in FIG. 14A , and the similar procedure is repeated.
  • the same advantages as those of the aforementioned embodiment are obtained.
  • the rotation position where the guiding is started, the rotation position where the guiding is finished and the like can be freely set, and a guiding mode can be finely adjusted.
  • the present disclosure may be applied to the rotary cutter apparatus in which the rotary body has the flat blade mounting portion arranged at a position away from the rotation axis on the plane crossing the rotation axis and arranged with inclination with respect to the rotation axis so that the radial dimension of the rotation trajectory by the end portion on the one side is larger than the radial dimension of the rotation trajectory by the end portion on the other side and the flat blade supporting portion supporting the first flat blade with respect to the flat blade mounting portion so that the end portion on the one side and the end portion on the other side of the first flat blade form the rotation trajectories having the same diameter by disposing the end portion on the other side of the first flat blade corresponding to the other side of the flat blade mounting portion so as to protrude more largely in the circumferential direction than the end portion on the one side of the first flat blade corresponding to the one side of the flat blade mounting portion, and the holding body is provided with a holding portion capable of holding the second flat blade so as to be substantially parallel with the rotation axis at
  • the end portion on the one side of the first flat blade and the end portion on the other side of the first flat blade form rotation trajectories having the same diameter and as a result, the first flat blade of the rotary body rotates for the whole area from the one side to the other side by keeping the substantially same distance from the rotation axis. Therefore, by introducing the object to be cut at the position away only by the predetermined distance which is the same from the rotation axis, substantially linear cutting can be applied to the object to be cut for the whole area from the one side to the other side of the first flat blade. In such rotary cutter apparatus, the same advantages as those of the above can be obtained by disposing the guide member 900 and the like.
  • the guide member 900 and the like may be arranged in an ordinary rotary cutter performing linear cutting by sequentially having each part of a spiral blade disposed on an outer periphery of a cylindrical body portion cut into the object to be cut. In this case, too, the same advantages as those of the above can be obtained.
  • the print label T was produced by applying a print on the label tape 3 A and cutting the same, but this is not limiting. That is, the present disclosure may be applied to a type in which a print is applied to a print-receiving tape and then, the tape is bonded with a base tape, and the bonded tape is cut so as to produce a print label T (so-called laminate type). In this case, too, the same advantages as those of the above can be obtained.
